True.  The TS11 driver works fine for TU80s.

That's true *only* regarding the transport hardware.  The TS11 and TU80
use a protocol called RSP (radial-serial protocol), as do TU58
cassettes.  It's *completely* different from TMSCP (tape mass storage
control protocol).  TMSCP is MSCP (like the UDA50) with additional
functions added to support tape operations.
